[SOLVED] Is this fan orientation okay? [Case Airflow]

[ageo]

I was testing a bunch of different fan orientations and this one in particular did the best in terms of cooling.
From the regular Neutral Airflow to this for comparison
37c to 29c idle and 58c to 51c load on the CPU.
40c to 38c idle and 65c load on both with the GPU.

Is it worth the cooling or is there problems with this?
Should I probably move any fans somewhere else?
I do care about dust but I do like seeing very low temps and everything performing at it's absolute best

This is the Neutral Airflow I compared to:

This is something else I tried, 32c idle 55 load CPU and same results on GPU:

Main issue here is, you have to turn radiator upside down. On top of the radiator air bubbles are collecting. That will impede liquid flow.

#1 - not sure, what's the idea with this setup. Doesn't really make sense;

#2 - makes most sense;

#3 - for this you have to install additional dust filter on rear fan. This setup would make sense, if vrms are overheating.

This case won't let me top mount aio sadly, but I've seen videos on stuff like that and it won't matter as long as the grill is above CPU placement

#1 is giving the best temps all around for every component, I just wish I could get a fog machine and see how it looks

That 360mm AIO will, over time, become noisier as the fluid volume goes down and more air collects at the inlet side of the radiator.
The noise will inevitably, force you to replace the unit early, even though there's nothing wrong with it functionally.


How do you know which diagram is positive/neutral/negative, etc? All three diagrams appear negative, just to different levels.

Oh I don't know, when I think I neutral, I just think of what mostly EVERYONE is doing, intake at the front and exhaust through the back

I am sad though that Phanteks P400a can't top mount, I wish I knew that before I got my AIO. I mean if I need to change the case in the future I will.

I just want to know the pros and cons of the #1 picture that I'm currently using right now

There's more to it than that, such as the fans used, how you will run your fans daily, the chassis' design, radiator placement, etc.

None per se, since you haven't reported any thermal issues, but what's likely going on up top is a bit roundabout - an airflow loop, because of that one intake fan up top.
So, some air is being pushed out the top, gets sucked right back in, and 2 things happen after that:
-some air loops right back out the top and repeats
-some of the air gets pushed out the back and can also be drawn back in by that top intake fan, and repeats

this will definitely be taking place with this setup.
and if the rear and\or right-side is close to a wall this effect will be even worse.

the warm air will be rising along the wall from the rear and get sucked right back into that top intake
along with the warm air being exhausted right next to it.
this will cause some of that warm air to be continually recycled and can end up getting warmer and warmer over time.

I am sad though that Phanteks P400a can't top mount, I wish I knew that before I got my AIO.

if you've purchased recently;
exchange the AIO for a 280mm and top mount it.
or exchange the case for one with 360mm mounting points.

Mine isn’t close close to the wall so maybe that’s why I haven’t been having any of the stated issues that could happen.
Btw, this is on the Ryzen 7 5800x and I’ve been running this all day and the temps have been consistently the same
